Class B First-hand BFRO #1237

While standing on the deck of vacation home man hears eerie human-like calls

September 2000 about 11:00 AM Eleven Mile Resevoir, Park County, Colorado 1 witness

Account

The witness was standing on a deck overlooking a reservoir in the morning when an extended human-like animal call was heard from a nearby forested area. The sound lasted several minutes and was described as spine-tingling, lost-sounding, and unlike anything heard during extensive hiking and camping experience. No animal was seen.
